2. A "new" car doesn't have 5,000 miles on it. They told me it was new. There was no ambiguity there. They pushed the papers at me hoping I wouldn't notice it.
3. Illegal or not, that's what they did on the next day final paperwork. Of course, they said it was just a clerical error and they'd fix it. The original deal was not documented.
4. When you have a column of numbers and a total, the total should match the sum. There's no excuse for this.
These issues were from multiple dealerships, so I figure it is common practice. One was from a friend of mine, who I warned to check the numbers on the final next day paperwork. He laughed at me, saying nobody would do that. The next day he called and thanked me, as he discovered a $1,000 error in the dealer's favor. He said he'd have never checked it if I hadn't warned him.
